Ball valve bulkhead fittings for $15 from Lowes!! built 2 today, seal perfectly, I cannot wait to use them with my 10 gal system! See here for the parts detail! Pics to follow....
(1) A-836 1/2"MIP x 1 1/2" Brass pipe nipple (goes through cooler wall)
(1) 1/2" x 1/2" FPT x Barb female adapter (hose barb for insife cooler)
(2) 3/4" SS flat washer (one on the outside and one inside to compress grommet to cooler wall)

(1) 1/2" x 1/2" MPT x barb Male adapter (for outer hose barb)
(1) 1/2" threaded ball valve (this sis obvious)
I know, I will, they look and operate GREAT! My 4 year old daughter helped me pick the parts and carry them through the store... ha ha. I went to take pics of the assembly and my digital camera was dead thanks to pictures of the kids playing in our snpw before it melts tomorrow. I will be home next weekend and will try to get those pics up there to help out. My previous system never had ball valves, just the little plastic "pinch" valves that crimp the hoses, what a PAIN!!!! Now I can set my ball valves and just reeeeelax!
I decided to make my own washers when I couldn't find one. I chose Lexan which is practically unbreakable but flexable. I felt like it needed the flexability to conform to the curvered wall of the cooler. I really had to tigthen the heck out of it to make it stop leaking. But it seems to be working and holding up well.
